AI Article Synopsis

  • The study aimed to identify physical and socioeconomic factors affecting birthweight in Tokyo, Japan, by surveying 553 pregnant women in their third trimester.
  • Results indicated that low pre-pregnancy weight, low income, and having a female infant were significantly linked to lower birthweight.
  • The findings highlight that income plays a crucial role in determining birthweight in Japan, suggesting it as an important factor for future research and health policy.

Article Abstract

Background: The purpose of this study was to characterize physical and socioeconomic factors associated with birthweight in Tokyo, Japan.

Methods: In a cohort of obstetric outpatients from the Tokyo Metropolitan Maternity and Child Health Institute, Tokyo, and The Jikei University School of Medicine, Chiba, Japan, 553 eligible women in their third trimester of pregnancy were given a survey investigating physical and socioeconomic backgrounds.

Results: Infants tended to be small for gestational age when maternal pre-pregnancy weight was lower, and low income and female infant gender were significantly associated with a low birthweight infant. Further, birthweight compared with predicted birthweight was lower in the case of a female infant gender, low income, low maternal pre-pregnancy weight and low parity.

Conclusion: Income is a novel parameter that is associated with birthweight in Japan.

The most frequently reported post-coronavirus disease of 2019 (COVID-19) symptoms include shortness of breath, fatigue, and cognitive disturbances, with reports of persistent dyspnea ranging between 26% and 41%. There is an urgent need to understand the risk factors and predictors for persistent COVID-19 dyspnea in individuals at all levels of COVID-19 illness severity, to enable the implementation of targeted interventions for those likely to be most affected with persistent dyspnea. Thus, the purpose of this systematic review is to explore the risk factors and predictors that are associated with persistent dyspnea in the post-COVID-19 population.
